摘　　要：随着矿产资源的开发利用,我国矿产资源贫、细、杂的特点日渐突出,其中微细粒矿物的高效回收成为选矿领域亟待解决的难题。微纳米气泡因独特的表面和体积特征,在提升微细粒矿物浮选效率方面展现出显著优势。在综述了微细粒矿物定义、性质及其分选现状基础上,详细介绍了微纳米气泡的特性、产生原理及应用,并着重探讨了微纳米气泡在浮选过程中促进微细粒矿物浮选的作用机理。结果表明:微纳米气泡可直接粘附于疏水颗粒表面,有效增强颗粒与气泡间的碰撞频率,并降低颗粒脱离气泡的概率;微纳米气泡在复杂溶液环境和物理压力下具有超常稳定性,这为浮选过程的强化提供了保障。最后提出了未来微纳米气泡浮选技术的研究方向,研究可为微细粒矿物的高效分离回收提供理论指导和技术支持。With the development and utilization of mineral resources,the characteristics of China's mineral resources being poor,fine and complex have become increasingly prominent.The efficient recovery of micro-fine minerals has become an urgent problem to be solved in the field of mineral processing.Micro-nano bubbles show significant advantages in improving the flotation efficiency of micro-fine minerals due to their unique surface and volume characteristics.On the basis of summarizing the definition,properties and separation status of micro-fine minerals,the characteristics,generation principle and application of micro-nano bubbles are introduced in detail,and the mechanism of micro-nano bubbles promoting the flotation of micro-fine minerals in the flotation process is emphatically discussed.The results show that micro-nano bubbles can directly adhere to the surface of hydrophobic particles,effectively enhance the collision frequency between particles and bubbles,and reduce the probability of particles leaving bubbles.Micro-nano bubbles have extraordinary stability under complex solution environment and physical pressure,which provides a guarantee for the strengthening of flotation process.Finally,the research direction of micro-nano bubble flotation technology in the future is proposed.The research can provide theoretical guidance and technical support for the efficient separation and recovery of micro-fine minerals.
